n for the three days to be 5 miles
1 answer:
Answer:
3.8 miles
Step-by-step explanation:
Given data
Saturday= 4 4/5 miles= 24/5= 4.8 miles
Sunday= 6 2/5 miles = 32/5=6.4 miles
Monday= x miles
Average= 5 miles
We know that
Average= Sum of data/Number of data
5= 4.8+6.4+x/3
cross multiply
5*3= 4.8+6.4+x
15= 11.2+x
x= 15-11.2
x=3.8 miles

Answer: D
Step-by-step explanation:
2x^3y+18xy-10x^2y-90y
= 2xy(x^2 + 9)- 10y(x^2 + 9)
= (x^2 + 9)(2xy - 10y)
= (x^2 + 9) 2y(x - 5)
= 2y (x^2 + 9) (x - 5)
